GIGABYTE's leading 12 phase power VRM design utilizes the highest caliber components to provide unadulterated, smooth power delivery for the CPU. GIGABYTE's 12 phase power design enables better delivery of power to supercharge your system, giving power users unparalleled overclocking ability and lower temperatures to reach maximum performance levels.The 12 phase power VRM has been designed and engineered to deliver fast transient response times through quick and seamless power delivery during extensive CPU loading variations. In addition, heat from the VRM is effectively reduced by spreading the load between the 12 power phases, resulting in a cooler and more stable platform.

On/Off Charge Technology

GIGABYTE On/Off Charge technology allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off. A derivative of GIGABYTE's highly acclaimed 3x USB Power feature, On/Off Charge enables devices to draw more current from GIGABYTE motherboard USB ports than standard USB ports allow, so that charging from your PC can be as fast as with a charger...more
*Due to certain mobile phone limitations, users may need to connect the mobile phone to their PC before the PC enters S4/S5 mode to enable a quick charge from non On/Off Charge USB ports. Charging results may vary by model.
*Whether to support 3X USB power design, it may vary by models.

On/Off Charge USB port

Charges iPad, iPhone and iPod Touch while PC Hibernates or even when shut down (off).

USB 3.0 Support

The GIGABYTE motherboards support the latest generation SuperSpeed USB 3.0 technology made possible through an onboard USB3.0 host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience an almost a 10x improvement over USB 2.0. Additionally, backwards compatibility with USB 2.0 assures users of long term use of their legacy USB 2.0 devices. The onboard SuperSpeed USB 3.0 technology also provides new power management features that include increased maximum bus power and device current draw to better accommodate power-hungry devices.
* USB 3.0 10x performance is a maximum theoretical value. Actual performance may vary by system configuration.

GIGABYTE motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. GIGABYTE’s unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery.

Ultra Durable 3

GIGABYTE Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE's Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking...more

Cloud OC

GIGABYTE Cloud OC is a free overclocking application that facilitates PC overclocking through any web browsing capable device such as a smart phone, iPad, iPhone, Netbooks or notebook PC. Being browser based, it connects via wireless Internet, Bluetooth or through an Ethernet cable, and its many functions are categorized into three tabs: Tuner, System Info and Control...more

Hotkey OC

GIGABYTE Hotkey OC allows users to create and save various profiles that can be adopted for different benchmarks. Hotkey OC then allows users to jump between these profiles on the fly so that the best profile for each segment within the benchmark can be used to optimize scores and boost overall performance. For example, when running 3DMark 06, the 1st profile might be optimized for graphics, and can be used for the first two graphics tests, then, the next two tests can utilize the 2nd profile which might be optimized for CPU tests, and one could jump back to the 1st profile again for the final two graphics (shader) tests...more

Support Intel Core™ i7/ Core™ i5 processors delivering native support for DDR3 memory up to 2200+MHz by the enhanced design of GIGABYTE, Intel Core™ i7/ Core™ i5 processors feature the memory controller integrated directly into the processor die, rather than as part of the Northbridge as in previous generations, allowing for faster memory performance. * Please refer "Memory Support List" for memory support information
